Evidence summary
Why P3 Labs is rated 8.5/10
Our conclusion
P3 Labs has a functioning US storefront, 18 issuer-matched BioViridian reports, 17 exact current listing controls, published company details, clear shipping terms, and a verified 10% checkout code.
The evidence supports 8.5/10. COA practices are the strongest facet, with an exact certificate control for every current listing. The main limitations are narrow laboratory panels, a young domain, and no reliable independent customer-review record yet.
Verification notes
What we reviewed, with the limits of that evidence kept explicit.
01
BioViridian certificate archive
P3 Labs publishes 18 one-page BioViridian certificates dated August 6 through September 5, 2026. Every document names P3 Labs or P3 Labs LLC and matches an official BioViridian laboratory PDF. Each report includes LC-MS/MS identity, RP-HPLC purity, and HPLC measured-content results. Seventeen current product-and-strength rows receive exact controls. An older NAD+ 500mg report stays in the filtered library as historical evidence. The archive does not include endotoxin, sterility, or heavy-metals panels.
P3 Labs does not yet have a reliable exact-domain independent customer-review record. The complete issuer-matched certificate archive, functioning checkout, and published company details support the owner-set 7/10 reputation factor, while the July 22, 2026 domain registration keeps the operating history short.
03
Shipping, payment, and checkout
Checkout ships to the United States and Puerto Rico. On September 18, 2026, it showed UPS Ground for $6.50, UPS 2nd Day Air for $10, and free shipping from $250. Stripe checkout supports credit and debit cards, Apple Pay, Google Pay, Amazon Pay, and Link. Code PEPTIDEPRICES removed $3.50 from a $35 BPC-157 cart, exactly 10%, and the issued referral link saved the discount automatically. No order was placed. Sales are generally final; damaged, defective, or incorrect-order claims require notice within five calendar days, and confirmed lost packages are reshipped.
04

The storefront publishes P3 Labs LLC, 332 W Commercial St, Broken Arrow, Oklahoma 74012, plus email and phone support. Its terms name Oklahoma law.
